INDUSTRIAL EXPOSITION.
The Students of the Public School Dis
play Their Genius.

AAt uhiAC SLibbAs uuutI TIE guiding
hand of Prof. Friedel, gave one of the
most charming exhibitions on Friday
and Friday evening last ever given i'm
this city. The exhibition consisted
largely of the handiwork of the stu
dents who, under Prof. Friedel's in
structions have made proficiency in
mechanical and scientific work, the
leading features OF which we will
briefly describe.
Among the articles exhibited made
in the school workshop was a large
HOltz Electrical Machine. constructed
by Prof. Friedel. which is beyond
doubt one of the best of the kind in
the Northwest. The machine is con
Structed with double revolving plates,
"a inches in diameter, and two sta
tlonary upright plates 81 inches in
diameter. It has two adjustable
electrodes capable of motion in any
direction. With the proper use of the
Leyden jars this machine is capable
of giving disruptive discharge of
from ii to Is inches.
The plan of this machine is to
large extent original with Prof. Erie
del, and contains many points of ex.
cellehce, not the least of which is the
ease with which it can be put together
and in working order.
The cost of this machine as quoted
in the catalogue Of Queen Il Co. would
not be far from $3.50. 1t is the prop
erty Of the High school.
Another object of interest on exhi-
bition was the stationary Electric
Engine, constructed by Lyman Powell.
assisted by Newell Powell, Levi Lem.
Fred. Davis and others. This engine
Is made of two vertical electro mag
nets, above which six armatures of
soft iron revOlve. These armatures
are set in motion by six successive
Impulses from the magnets for each
revolutions; the impulses being caused
by the current breaker, Il little instru-
menJ made of brass and hard rubber, |
and situated at the end of the reVoly. |
ing shaft. The current breaker. as |
it TevOiyes. rubs against two small |
springs. thus alternately making and
breaking the current. This little en-
CINE was set in motion during the |
exposition and was very generally
admired by the large assembly of peo-
pie who were present during the even
ming.
A "whirling machine" constructed |
10y Levi Lem was exhibited which |
beautifully illustrates the principle of |
the ''sO-called" centrifugal force. |
This machine is constructed with "A |
vertical iron axis set in neat wooden |
frame. At the bottom of The axis is |
a ring of iron to which are attached |
large brass, spiral springs in such a |
way as TO reyOlye with the axis. These |
springs are attached at the top to a |
ring OF iron which is free to move Oh |
the axis. The machine is set in mo-
ton by friction pulleys, and when
whirled rapidly the springs bulge out |
at the center. thus assuming the shape |
of an oblate spheroid.
An electric Motor Engine in process

Patterson, Levi Lem and others. not /
having been completed as anticipated |
could not be exhibited and its absence |
from the program caused much regret. |
as 1t was expected that it would be one |
OF the most interesting features of the /
exhibition. 1t is the intention to have |
this little engine completed in the near |
future, and 1t will then be run on |
wire track the length of the large |
room for the benefit of the Physics |
class and for the pleasure of visitors.
The induction coil made by Prof. |
Fleidel and attached to . pail Of water |
afforded much amusement through the |
futile efforts of the plucky ones who |
tiled to extract coin from the water.
\ telegraph line constructed by the |
boys in the mechanical department. |
and connecting the basement with the |
high school room, was in working |
order, over which messages were con- |
veyed in regular business style, much |
to the credit OF the boys whose genius |
constructed the line.
Relative to the workshop connected |
with our Public School we feel in |
ciined to claim that it is a step in |
advance which is not only very cred |
liable to Prof. Freidel and an exhibit |
ton of energy and good judgment OH |
his part, but that il is one of the most |
valuable departments in the school. |
The work undertaken there is rousing |
into action the genius of the boys. and |
creating spirit of emulation and |
wholesome strife Tor superior attain |
ments which must result in great |
benefit to them, without interfering |
in the least with other studies, as the |
other studies are absolutely essential |
to their rapid and permanent progress |
in the mechanical undertakings in |
which Prof. Ereidel engages them; |
thus 1t must prove great help rather |
than hIndrance to other branches of |
education, and will, in the years to |
come. be "a source of pleasant recol- |
lectiOns to all those who now make |
5JOd use of its advantages.
The crayOning of the Two Little
GOssips," by Josie johnson, was uni |
veTsally admired, and was certainly
one of the finest of the many beauti-
full things TO be seen at the exhibit.
and in its execution Miss Johnson did
herself great credit. The faces were
copies, but the remainder of the de-
sign was original. The fine frame
it. 10y 5 y it. in which the picture was
set, was manufactured by members of
the High school.
This beautiful picture is now hung
in the High School, and we under
stand that it is the intention to fur
ther decorate the walls in a similar
manner as from time to time students
shall complete acceptable works of
art.
Below we give a list of students
names with the articles they have
manufactured:
